UNITED STATES PATENT OFFICE.

EARL A. AVERILL, OF MOUNT VERNON, NEW' YORK, ASSIGNOR TO LOCOMOTIVE FEED WATER HEATER COMPANY, OF WILMINGTON; DELAWARE, A CORPORATION OF DELAWARE.

To all whom it may concern:

Be it known that I, EARL A. AvnluLL, of

. Mount Vernon, in the county of VVestchester and State of New York, have invented a certam new and useful Improvement in Locoinotive-Feed-Water Heaters, of which improvement the following is a specification.

My invention relates, generally, to locothe heating medium, and, particularly, to

constructions of that type which accord, in operative principle, with that set forth in an application for Letters Patent of the United States filed by me under date of January .26, 1918, Ser. No. 213,872. The

object of my present invention is to provide u an apparatus of the general character of that of my application aforesaid which shall embody simple and reliable means for eifecting the delivery of the condensate from the heater to a receptacle in which it is freed from the proportion of lubricating oil which passes into the heater with the exhaust steam.

The improvement claimed is hereinafter fully set forth.

. In the accompanying drawings: Figure 1 is a diagrammatic side view of a locomotive 30.

engine and tender, illustrating an application of my invention; Fig. 2, a similar front view of the locomotive; Fig. 3, a diagrammatic view of the lower forward portion of the locomotive, with cylinder and valve chest removed; Fig. 4, a vertical central section, on an enlarged scale, through the condensate delivery mechanism; Figs. 5 and 6, horizontal sections, on a further enlarged scale, on the lines :0 a: and y y respectively of Fig. 4, and; Fig. 7, a diagrammatic view, showing a supplemental delivery tank.

My present invention is, similarly to that of my application Ser. N0. 213,872 aforesaid, designed to enable the entire volume of the condensed steam to be freed from contained lubricating oil and returned to the tender tank, for succeeding supply to the heater and thence to the boiler. It is herein exemplified as applied in connection with a feed water supply and heating system, which, in and of itself, is not claimed as of my present invention, said system comprehending a feed water heater, 1, which may be of any suitable and preferred construction, and which is located near the cylinders,

Specification of Letters Patent.

LOCOMOTIVE-FEED-WATER HEATER.

Patented July 8, 1919.

Serial No. 226,826.

preferably in front of and below the smoke box A, of a locomotive boiler, A. Feed water is drawn from the tender tank, B, through a supply pipe, 2, by a pump, 3, which forces it through a delivery pipe, 4:, into and through the heating elements of the heater, 1, which may be of tubular or other known construction of the well known surface type, in which elements it is subjected to the action of exhaust steam, supplied through pipes, 5, and thence passes through a pipe, 6, to and past a check valve, 7, and into the boiler. The condensate of the exhaust steam passes out of the heater through a drain pipe, 8, which, in ordinary practice, drops it upon the tracks.

In the practice of my invention, referring descriptively to the specific embodiment thereof which -is herein illustrated, the drain pipe, 8, instead of having, as in ordinary practice, its discharge end open to the track, is extended rearwardly, and is connected to, and forms the supply pipe of, a fluid pressure forcing delivery mechanism, which is inclosed in a delivery tank, 9, said mechanism, which will be presently generally described,being located at any point below the level of the bottom of the heater. A delivery pipe, 10, leads from the forcing mechanism to a filter, 11, of any suitable and preferred construction, which is preferably, as shown, supported on the top of the tender tank, B. A water discharge pipe, 11, leads from the filter, into the tender tank, and the oil which is separated from the condensate, in assing through the filter, is with drawn t erefrom through a passage controlled by a cook or valve, 11".

The construction of fluid pressure forcing delivery mechanism which is shown in Figs. 4, 5 and 6, is one which is desirably adapted for practical service, and its principal elements comprise a closed delivery tank, 9, with pipe connections to the drain pipe of the heater and to the filter delivery pipe; check valves interposed in said connections; a valvular mechanism for alternately imposing fluid pressure on, and relieving it from, the delivery tank; a float supported on the water of the delivery tank and adapted to actuate the valvular mechanism; and an equalizing reservoir interposed in the line of the heater drain pipe, between the heater and thedelivery tank, in which condensate, accumulated during the periods of discharge from the delivery tank, may be retained.

The fluid pressure delivery mechanism illustrated in Figs. 4, 5, and 6, and hereinbefore generally described, is not, in and of itself, claimed as of my present invention, and the same constitutes the subject matter of a divisional application filed by me November 22, 1918, Ser. No. 263,691.

The improvement herein set forth presents the advantages of separating the oil from the condensate of a locomotive feed Water heater and preventing the objectionable results of the drainage of condensate upon the track, or escape of uncondensed steam, by an apparatus, the construction of Which is simple and inexpensive; Which may be readily applied Without interference With other members of a locomotive; and Which embodies 110 parts Whichinvolve undue cost of maintenance or liability to failure in operation.

I claim as my invention and desire to secure by Letters Patent:

1. In a locomotive feed Water heating system, the combination of a feed Water heater;

a feed Water supply receptacle; means for effecting the supply, in separated currents,

of feed Water and of exhaust steam to the heating elements of the heater; means for separating lubricating material from the condensate of the exhaust steam; a drainage cOnduit connecting the heater With said separating means; a delivery mechanism, in

.terposed in said conduit, for directly applying fluid pressure to the condensate therein, and thereby forcing it from the conduit to the separating means; and means for delivering the condensate from the separating means to the supplyreceptacle.

2. In a locomotive feed Water-heating system, the combination of a feed Water heater; a feed Water supply receptacle; means for effecting-the supply, in separated-currents,

of feed Water and of exhaust steam to the heating elements of the heater; means for separating lubricatln-g material from the effecting the supply, in separated currents,

of feed Water and of exhaust steam to the heating elements of the heater; means for separating lubricating material from the condensate of the exhaust steam; a drainage conduit connecting the heater with said separating means; a fluid pressure delivery mechanism, automatically operable by variations of level of the condensate, for forcing condensate from the conduit to the separating means; and means for delivering the condensate from the separating means to the supply receptacle.

l. In a locomotive feed Water heating system, the combination of a feed Water heater; a feed 'Water su'pply receptacle; means for efl'ecting'the supply, in separated currents, of feed Water and o f exhauststeam to the heating elements of the heater; means for separating lubricating material from the condensate of the exhaust steam; a drainage conduit connecting the heater with sald separatlng means; an automatically operable float actuated fluid pressure delivery mechanism, interposed in said conduit, for forcing condensate therefrom to the separating 'means; and means for delivering the condensate from the separating means to the sun ly receptacle. 7 r l p EARL A.
